Monash’s research could transform how broken bones are treated, with the development of a dissolved material based on special zinc that could replace the typically used metal plates and screws to keep fractured bones together.
Surgeons routinely use stainless steel or titanium, which remain in the body forever, can cause discomfort and may require monitoring surgeries. A new zinc alloy, designed by Monash biomedical engineers, could solve these problems by being mechanically strong but soft enough to degrade safely over time while supporting optimal healing.
A study published today in Nature It shows the innovative approach of the research team to make Zinc alloy as strong as permanent steel implants and more durable than other biodegradable options such as magnesium -based implants.
Principal researcher, Professor Jian-Feng Nie, of the Department of Materials Science and Engineering, said that the innovative material had the potential to transform orthopedic attention by reducing complications, minimizing the need for additional surgeries and offering a sustainable alternative to Permanent metal implants.
“Our zinc alloy material could revolutionize orthopedic care, opening the door to safer and smaller implants that not only improve the patient’s comfort, but also promote better healing results by minimizing the interruption of surrounding tissues,” Said Professor Nie.
“An implant that never disappears will always be a risk to the patient. On the other hand, one that degrades too fast will not allow adequate time for bones to heal. With our zinc alloy material, we can achieve the optimal balance between force and controlled implant degradation to promote better healing. “
The research shows that the engineering of the size and orientation of the grains of the material, the alloy of zinc can be fold and adapt uniquely to accommodate the shapes of their neighboring fabrics.
“This did not only stronger but more flexible, offering an alternative that changes the game for orthopedics,” said Professor Nie.
The research is raiding the way for a new company at Monash University with an approach to the development of next generation biodegradable implants.
